I've also had the whole body tingle before. When something really touches me emotionally, I get this.... it lasts for a few minutes... weird.
I have had buzzing, tingling and very sensitive painful skin areas, which has all settled down. My latest thing is what feels like "chills" travelling down my left leg occassionally, which seems to be on a schedule of every 3-4 mins when it happens.
Nerves are strange little things when they are traumatized and/or healing.
